The new multi-laser engine iChrome SLE from Toptica supports multi-colour applications that require separate microscope input ports (FRAP, TIRF, confocal microscopy / spinning disk, for example). It offers up to eight different wavelengths from a broad range (405-640nm) and up to 70mW per colour out of the fibre.
Each laser source is housed in an individual, field exchangeable cartridge, while the integrated fibre switch enables fast switching of all colours between two SM/PM fibres within less than 10ms. It can also be used for advanced scientific setups where one laser engine is used to drive different devices without the need to swap fibres.
A uniform user interface controls all integrated laser sources of the iChrome SLE, making all lasers appear equal to the user, regardless of the technology behind the laser source (DPSS or diode laser). Customers can choose from a variety of interfaces: USB, RS232, Ethernet, analogue and digital ports. The microprocessor-controlled system enables flexible OEM integration into systems such as microscopes or flow cytometers for demanding cell biology applications requiring multiple wavelengths, while high-speed analogue and digital modulation with up to 250kHz allows fast switching of laser wavelengths and intensities.
Toptica’s Coolac technology automatically aligns the system at the push of a button and eliminates the need for manual readjustments, enabling plug-and-play capability, push-button installation and long-term operational stability.
